VEHICLE-WHEEL.

SPECIFICATION forming partof Letters Patent No. 269,373, dated December19, 1862. Application tiled February 6,1882. (No model.)

To all whom it may concern:

Be it known that we, EDWARD BADLAM and DAVID E. SOUTHWICK, ot'Ogdensburg, in the county of St. Lawrence and State of N ew York, haveinvented certain new and useiul Improvements in Wheels for Vehicles; andwe do hereby declare that the following is a full, clear, and exactdescription ot' the invention, which will enable others skilled in theart to which io it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which- Figure l is a longitudinal section of thehub of aVehicle-wheel ot' ourim proved con struction. Fig. 2 is across-section of the hub through line wx in Fig. 1. Fig. 3 is asectional view of one of the spokes, with its socket for attaching it tothe felly. Fig. 4 is a detail view of the rubber-cushionedspring-ferrule which forms the core ofthe hub; and Figs. 5, 6, and 7 aresectional views of the spoke-tenons, illustrating modifications in theconstruction and shape of lthe same.

Similar letters ot' reference indicate corresponding parts in all thefigures.

Ourinvention contemplates animproved construction of vehicle-wheels, andhas for its object to combine durability of construction with acertaindegree of elasticity, so as to provide a smooth-running wheel, which maybe easily taken apart, when desired, for the purpose of repair, and aseasily put together.

To this end our improvement consists in the construction and combinationof parts, hereinafter more fully described and claimed.

In the accompanying drawings, Arepresents the axle-arm, which, it' notmade of steel or iron, should have the usual thirnble-skein.

B is the axle-box, which is screw-threaded on the outside, the threadsruiming in dierent directions on opposite sides of the hubbody. In otherwords, it has a right-handed screw-thread on one side of this and aleft-, hand thread on the other side.

The hub is composed of ve concentric parts or sections-viz., an outersleeve, C, which is cast or made in one piece with the nut-sleeve c, andhas a swelled rim or annular shoulder, C', on its inner side, acorresponding sleeve, D, vwhich has, likewise, a swelled rim or annularshoulder or ange, D', and is made in one piece `usual.

with the said box D2, and a central part or body composed ot' threedisks, F, G, and H, which are clamped between the parts C U and D D', asclearly shown in Fig. 1 0f the drawings. Box B, with its several partsofthe hub, is held upon the axle by a iianged nut, E, as

The middle part of the hub or hubbody, which -receives the spokes, is,as above stated, composed of' three disks, F, Gr, and H, each of whichhas a central circular bore or aperture. The disks are concentric, andtheir several central apertures register with one another. The two outerdisks, F and H, have semicircular radial recessesfh, while the centraior middle disk, G, has a double series ot' similar radial recesses-oneseries on opposite sides or faces, as shown respectively at g and g inFig. 1, those on one side alternating with those on the other side. rIhehub-disks F, G,

and H are so placed upon or against one-Y another that the radialrecessesfot' disk F will register with the radial recesses g on thecontiguous side or face of disk G, while, again, the radial recesses gon the opposite side of the latter will register with the radialrecesses h of disk H. Thus two rows of alternating bores areformed-viz., fg and g L-radiatin g from the center of the hub andextending from its circumference to the central aperture. In to thelatter is inserted a sleeve or ferrule, J, made of steel or othersuitable spring metal, which is split longitudinally on one side, asshown atj, and is provided with an interior rubber packing, K. Leather,felt, or other suitable material may be used instead of rubber for thering or packing-sleeve K, if desired. The axle-box B is inserted throughthe packing-sleeve K, and rotates with it and the hub.

I I are the spokes, the inner tcnoned ends, i, of which arescrew-threaded, and are screwed into the radial bores or recesses fgandg' h, which are likewise screw-threaded to receive them. The spokes arescrewed in far enough to cause their inner ends to impinge upon thespring sleeve or t'errnle, J, as shown in Fig. 2. In Fig. 3 we haveshown the outer end ofA one ot' the spokes, with its clamp or socket,felly, and tire. The spoke I is reduced, as shown at i', to form a tenonwhich will lit tightly into the socket L, which is made with daringwings l Z, and a tapering thimble, l', between said wings.

M is the telly, which is shaped to t between IOO the wings orsocket-clamps ZZ, and N is the tire, which has a countersunk hole, n,for each spoke.

m is along screw, which may be either tapering or of even sizethroughout its length. This screw or screw-bolt is inserted through ahole bored through the felly and tire, through the tapering thinible l',and up into the spoke7 as clearly shown in the drawings.

The spokes may he made of steel, iron, or wood, as desired, and it' madeof metal they may be either solid or hollow. In Figs. 5, 6, and 7 wehave shown cross-sections of the tennned ends i ot' the spokes, the twofirst-named figures representing sections through tubular steel spokes,and Fig. 7 a cross-section through a wooden spoke. The sleeve or ferruleJ being` split or slitrefi on one side permits it to give or yield toinward pressure ofthe spokes, and of their disks F, G, and H, the insideelastic core forming a cushion around the middle part of the axle-box.Thus we provide for an elastic and smooth-running wheel, the tire ofwhich may be tightened'by screwing the spokes up in their respectivethreaded sockets.

It is obvious that two hub-disks may be usedinstead ot three, in whichcase of course the radial spoke-recesses of one register with those ofthe other.

Having thus described our invention, we claim and desire to secure byLetters Patent of the United States- In a wheel for vehicles, thecombination of the axle-box B, hub-sleeves C C and D D', elastic oryielding hub=core J K. and two or more concentric hub-disks, F G H,having radial semi-cylindrical or tapering recesses on their contiguousfaces registering with one another, said disks being clamped betweensleeves C O and D D', substantially as and for the purpose herein shownand described.

In testimony that we claim the foregoing :is our own we have heretoaffixed our signatures in presence of two witnesses.
